Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If external blower or exhaust fan devices are connected to the fresh air port or air outlet to disperse heat, then heat dissipation and cooling are achieved, but temperature differences between products increase and test result accuracy decreases
Solution Approach 1:
The patent introduces a circulating air duct as an intermediary structure that mediates between the fresh air port and air outlet. This duct guides air flow through a controlled path, ensuring uniform distribution of cooling air across all test positions without direct external blowers creating turbulent flow and temperature disparities.
Solution Approach 2:
The air outlet is divided into multiple outlets distributed at different positions within the circulating air duct. This segmentation ensures that cooling air is delivered uniformly to various test positions, eliminating temperature differences between products while maintaining effective heat dissipation.
2Temperature
If external devices are used to assist in heat dissipation, then heat dissipation is improved, but energy consumption increases and test costs increase
Solution Approach 1:
The circulating air duct serves multiple functions: it acts as a heat dissipation channel, a temperature uniformization system, and an air flow distribution network. By integrating these functions into a single structure, the patent eliminates the need for separate external blower or exhaust fan devices, thereby reducing energy consumption while maintaining heat dissipation performance.
Solution Approach 2:
The circulating air duct utilizes the natural convection and pressure differential within the test chamber to drive air flow. The system self-regulates heat dissipation without requiring external powered devices, achieving energy-efficient cooling through the inherent airflow patterns and thermal gradients within the enclosed space.
3Use of energy by moving object
If fresh air port and air outlet are provided in a circulating air duct without external devices, then energy consumption is reduced, but airflows inside the box body cannot be smoothly discharged leading to poor heat dissipation
Solution Approach 1:
The patent employs a baffle device that can dynamically adjust the opening degree of the fresh air port and air outlet. This dynamic adjustment optimizes the balance between energy consumption and heat dissipation efficiency by adapting the airflow characteristics to different testing conditions, ensuring smooth air discharge while maintaining low energy usage.
Solution Approach 2:
The baffle device changes the geometric parameters of the air inlet and outlet openings by adjusting their opening degrees. This parameter modification optimizes airflow patterns, ensuring that air can be smoothly discharged from the box body while maintaining energy-efficient operation. The opening degree is tuned to achieve optimal flow characteristics for both heat dissipation and energy consumption.
